Y13 Claims.

The invention relates to a. sectional tobacco pipe in which smoke from the tobacco bowl is drawninto a smoke chamber and which is designed to have a drip receiving chamber for with- 5, drawing from the smoke chamber juices from the tobacco andany saliva which may drip through the pipe stem or mouth piece.

, The primary object of the invention is to provide a smoking pipe of the type outlined which .10. will afford a sweet, clean, dry smoke, free of odors or ilavors which characterize known forms of such pipes. Incidental to this general object, the disclosure features the providing of a construction which will trap the juices drained from the Y smoke chamber and for disposing the juices in such way in a receptacle therefor that they cannot iiow back into the pipe stem or into the to bacco bowl, even under those conditions where the pipe is laid on its side or inverted for the pur- 20. pose of cleaning the tobacco bowl of a previously burned charge of tobacco.

Incidental to the desire to have a form of pipe which can be maintained cool, particularly in the stem or mouth piece element, the invention features the providing of means for minimizing heat transference from the hot tobacco-containing bowl to the stem or mouthpiece.

Another object of the invention is to provide a simplied form of sectional pipe of the type outlined, the parts of which can be readily. de-

`mounted for cleaning.

Various other objects and advantages of the invention will be in part obvious from an inspection of the accompanying drawing and in part will be more fully set forth in the following particular description of one form of mechanism embodying my invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the accompanying drawing:

Fig. 1. is a view in Vertical axial section through a preferred embodiment of the invention, and showing the pipe with its bowl or body portion in normal, operative smoking position, and

Fig. 2 is a transverse sectional View through the body portion, taken on theV line 2--2 of Fig. 1 looking in the direction indicated by the arrow, and showing'the pipe lying on its side.

i, In the drawing there is'shown a holder 10, pref- -f "erably made of wood, and including a tubular cylindrical body portion 11, internally threaded at opposite ends, as indicated at 12 and 13. The holder also includes as an integral part thereof la stem receiving tubular extension 14 projecting from one side of the body portion 11. The outer portion of the bore of the tubular extension 14 is of cylindrical form as shown at 15, and thel portion of the bore between the cylindrical por tion l5 and the body portion 11 is of frusto-conical form as shown at 16, with the small end openu ing into the portion 1l between the threads l2 and 13.

A tobacco bowl 17, preferably formed of meerscnaum or equivalent heat-resisting material, is intruded into the upper end of the body portion 1l with its side wall externally threaded at theA central portion as shown at 18 and engaging the threads 12. The tobacco bowl projects above the top of the portion 11 and is provided at its upper end with an outlining flange 19 which engages the top of the portion l1 when the bowl' 1'? is screwed into position. The lower end of the toi bacco bowl tapers downwardly in the'forin of a cone and at its lowest point is provided-with a smoke and moisture discharging Vent 20.

Positioned below the bowl 17 is a drain section 21 which includes Van outlining ring 22, opposite ends of which are externally screw-threaded, as shown at 23 and 24, with an external ange 25 positioned between the threaded ends. The upper, threaded end of the ring 22'is screwed into the lower end of body portion l1, threads 13 engaging with threads 23 and with flange 25 in? abutting engagement with the lower end ofthe body portion l1. The section 21 also includes'ay downwardly tapering integral portion forming' a funnel 26 extending within and projecting down wardly from the ring 22, and provided at its lower smaller end with a juice-draining Yvent 27.V The funnel 26 extends downwardly in the same general direction as the bottom of the tobacco bowlA and coacts therewith to provide an annular smoke chamberv 28 of relatively large capacity.V The drain section 2l is preferably made of bakelite or equivalent hard, non-absorbing material It is herein suggested that the drain section 21 may be permanently secured to the body portion 11 as4 by glueing, so that the drain section 21 maybe regarded as a iixed part of the bowl holderl 10.

A juice-receiving receptacle 29 has an o'pen'f` top internally threaded, and is demountably Sel cured to the lower threaded end of the drain body portion to the pipe stem 33.

beetleware or equivalent hard, non-absorbing material, and particularly a material which will not retain tobacco odors. It is herein suggested that the holder, including the parts l0 and 21, be formed of aluminum, and it is obviously within the scope of the disclosure to form such holdler of one piece of material and where lightness of Weight is desired the entire holder may be made of bakelite.

A gasket is positioned between the abutting ends of the receptacle 29 and drain section 21, and the receptacle is also designed, when threaded into position, to abut the underside of ange 25, and in general the parts are designed so that when the several sections are assembled in their screw-threaded engagements there will be formed, in effect, a solid construction with neatly closed joints between the several sections. Another gasket 31 may be positioned between the bowl 17 and a shoulder 32 formed below the threads 12 on the holder 11.

A one-piece pipe stem or mouthpiece 33 formed preferably of hard rubber, has one -end inserted into the extension 14 and extends entirely therethrough so as to open into the smoke chamber adjacent its upper portion. The pipe stem 33 is twice reduced to form an outer shoulder 34 and an inner shoulder 35. The portion constituting the first reduction between these shoulders is of cylindrical form, as shown at 36, and has a snug but removable t in the cylindrical portion of the bore in the extension 14. From the shoulder 35 to. the inner end 37 of the stem 33 the second reduced portion 33 is slightly tapered, and is designed to engage the small end of the frustoconical portion 16 of the bore to provide a knife edge engagement 39 between the holder and the pipe stem. The portion 38 of the pipe stem is of less external diameter than the internal diameter of the portion of the bore 16 in which it is contained, so as to provide an annular air pocket 40.

knife edge engagement and air pocket providey heat insulating means for minimizing the transference of heat from the more or less hot The end 37 of the pipe stem projects slightly into the smoke chamber 28 beyond the inner wall of the body portion 11 to provide a drip edge 41 at the end 37, and this construction also tends to prevent the How of any juice in the smoke chamber from flow ing back into the bore 42 of the stem 33 under those conditions Where the smoker elevates the bowl above the level of his mouth while smoking.

It is particularly noted that the bore 42 of the pipe stem While it opens into the smoke chamber is otherwise out of communication with the interior of the receptacle 29, and as a result there is little if any possibility of juices escaping from thereceptacle and clogging or passing back through` the bore 42.

It is. alsol noted that the funnel 26 extends into the, receptacle 29, with the vent 27 centrally disposed therein but in spaced relation` to the outlining Walls of the juice-receiving compartment 43 inthe receptacle. The compartment extends upwardly about the funnel 26 and thus forms an annular catch basin 44 for retaining the juices Within the chamber 43 when the pipe is laid on its side, as indicated in Fig. 2, or when the pipe is; inverted in a position upside down from the showing in Fig. 1.

In operation it will be understood that the pipe isusedconventionally, the smoke from the burning tobacco in thev bowl 17 is withdrawn through vent 20;, smoke chamber 28, and bore 42.,Most. smoking tobacco contains tobacco juices, and when used in this pipe ow from the bowl 17 through aligned vents 20 and 27 and into the compartment 43 in the catch receptacle 29. It is also noted that saliva or drip which may accumulate in the bore 42 is permitted to drain therefrom into the smoke chamber and through the vent 27 into the receptacle space 43, as indicated by the arrows in Fig. 1. From this construction it is apparent that moisture and juices are drained out of the smoke conduits and discharged into the lower detachable receptacle from which they may be cleaned from time to time.

It is a feature of this disclosure, that the juices cannot escape out of the receptacle and are retained therein in all positions of the pipe. As noted in Fig. 2, the pipe, even with the receptacle partially lled with juices, can be laid on its side without danger of the juices flowing therefrom back into the other portion of the pipe.

The providing of the pipe stem 33 as a single integral unit permits the use of a construction which can be readily withdrawn from the remaining portion of the pipe to facilitate cleaning, but it is also apparent that the pipe in the form herein illustrated may have its pipe stem cleaned without removing it from the holder, or, if desired, access to the inner end of bore 42 may be provided by unscrewing the tobacco bowl, as will be necessary from time to time in order to thoroughly clean its tobacco receiving, compartment.

The knife edge engagement at 39 between the stem and holder at that portion of the holder which is most likely to be hot, provides a construction for bringing the. pipe stem in juxtapositionto the hot tobacco bowl 17, and at the same time tends to minimize heat transference to the pipe stem 33. The providing of the air pocket in the projecting extension, which itself is externally air-cooled, tends. further to insulate the hot inner end of the extension from the pipe stem, thus further assisting in maintaining the stem cool.
